5. “Airplanes,” B.o.B & Hayley Williams of Paramore
This song helped spread Hayley Williams’ wings — at least for me — as more than a front-person in an emo band. Her vocals on the chorus blend superbly with B.o.B’s rhyme flow. This track, about the downsides of fame, was inescapable during the summer of 2010.

4. “Clint Eastwood,” Gorillaz & Del tha Funkee Homosapien
Though we were lead to believe an animated band played this gem in the early ‘00s, it was a genius collaboration between real human beings: Blur’s Damon Albarn, producer Dan The Automator and rapper Del tha Funkee Homosapien. It wasn’t hard for the public to latch on to this one; it clicked on so many levels.
